DBField::prepValueForDB() and StringField::prepValueForDB() to ensure the field value is escaped correctly for the database. This means databases like MSSQL can introduce an "N" prefix (marking text as unicode to be saved correctly) by overloading the prepStringForDB method. MySQL, PostgreSQL and SQLite3 operate as usual.
